  • Patent number: 4957331
    Abstract: In an hydraulic anti-skid braking system (FIG. 1), a valve controlling the flow of braking fluid to a brake actuator is actuated by a pulse-driven stepper motor in response to signals emanating from a skid sensor. In a practical arrangement (FIG. 3), a motor under the control of a microprocessor actuates a pressure dump valve via an eccentric mechanism upon the appearance of a skid signal at the sensor, in order to de-pressurize the actuator, and also drives a pump which assists in re-pressurizing the system when the skid signal ceases.
